Abstract
A wheel and brake system is provided for a vehicle having a wheel with an inner wheel, an outer wheel generally concentric with the inner wheel, and a plurality of resilient members connecting the inner and outer wheels together for resilient movement therebetween. The wheel and brake system comprises a brake mechanism having a rotor and a caliper. The rotor rotates with the inner wheel and the caliper is rotationally fixed in position relative to the resilient wheel. An actuation system causes first and second rotor-engaging surfaces of the caliper to move toward one another to squeeze the rotor therebetween and to thereby resist rotation of the inner wheel.
Claims10
A wheel and brake system comprising:
- a wheel axle;
- an inner hub mounted to the wheel axle in a manner allowing rotation of the inner hub relative to the wheel axle about an axis of rotation;
- an outer wheel positioned generally concentric to the inner wheel;
- a plurality of resilient members connecting the inner hub to the outer wheel in a manner to permit resilient eccentric movement of the outer wheel relative to the inner hub, the resilient members also connecting the inner hub to the outer wheel in a manner so that the outer wheel rotates with the inner hub relative to the wheel axle;
- and
- a brake mechanism comprising a rotor and a caliper, the rotor being fixed to the inner hub in a manner so that the rotor rotates with the inner hub relative to the wheel axle, the caliper being rotationally fixed relative to the wheel axle and having opposing first and second rotor-engaging surfaces that are movable toward and apart from one another, at least a portion of the rotor being positioned between the first and second rotor-engaging surfaces of the caliper in a manner so that movement of the first and second rotor-engaging surfaces of the caliper toward one another causes the first and second rotor-engaging surfaces of the caliper to engage the rotor and squeeze the rotor therebetween to thereby resist rotation of the inner hub relative to the wheel axle.
A front wheel assembly of a two-wheeled vehicle comprising:
- a fork having first and second fork blades and a connection portion, the fork blades each having upper and lower end margins, the connection portion joining the upper end margin of the first fork blade to the upper end margin of the second fork blade;
- a wheel axle fixed to and extending between the lower end margins of the first and second fork blades;
- an inner hub mounted to the wheel axle in a manner allowing rotation of the inner hub relative to the wheel axle about an axis of rotation;
- an outer wheel positioned generally concentric to the inner wheel;
- a plurality of resilient members connecting the inner hub to the outer wheel in a manner to permit resilient eccentric movement of the outer wheel relative to the inner hub, the resilient members also connecting the inner hub to the outer wheel in a manner so that the outer wheel rotates with the inner hub relative to the wheel axle;
- and
- a brake mechanism comprising a rotor and a caliper, the rotor being fixed to the inner hub in a manner so that the rotor rotates with the inner hub relative to the wheel axle, the caliper being rotationally fixed relative to the wheel axle and having opposing first and second rotor-engaging surfaces that are movable toward and apart from one another, at least a portion of the rotor being positioned between the first and second rotor-engaging surfaces of the caliper in a manner so that movement of the first and second rotor-engaging surfaces of the caliper toward one another causes the first and second rotor-engaging surfaces of the caliper to engage the rotor and squeeze the rotor therebetween to thereby resist rotation of the inner hub relative to the wheel axle.
